This is totally something I ran into! I start with a simple Project 73 (increment the number always), then after I have started to get a good feeling of it, I name it something that sounds emotionally close to what the song feels like for me. I try not to overthink this part and just let it be whatever feels right.
From that point I can keep building/writing the song more, but at least now it has some identity.
